Subject: [Haskell-beginners] cabal install snap-server-0.9.5.1: At least the
following dependencies are missing: attoparsec >=0.10 && <0.13 && ==0.13.0.1
From: Stanislaw Findeisen
Hi
Could anyone explain this to me, please?
$ cabal install snap-server-0.9.5.1 Resolving dependencies... Configuring snap-server-0.9.5.1... cabal: At least the following dependencies are missing: attoparsec >=0.10 && <0.13 && ==0.13.0.1 cabal: Error: some packages failed to install: snap-server-0.9.5.1 failed during the configure step. The exception was: ExitFailure 1
Where does this unsatisfiable dependency come from? snap-server-0.9.5.1 seems to require just attoparsec (>=0.10 && <0.14): http://hackage.haskell.org/package/snap-server-0.9.5.1 . And attoparsec 0.13.0.1 is already installed:
$ cabal list --installed attoparsec * attoparsec Synopsis: Fast combinator parsing for bytestrings and text Default available version: 0.13.0.1 Installed versions: 0.13.0.1 Homepage: https://github.com/bos/attoparsec License: BSD3
* attoparsec-enumerator Synopsis: Pass input from an enumerator to an Attoparsec parser. Default available version: 0.3.4 Installed versions: 0.3.4 Homepage: https://john-millikin.com/software/attoparsec-enumerator/ License: MIT
I am trying to install hakyll 4.6.*, and snap-server seems to be one of the requirements. Hakyll 4.6.* is an old version but AFAIR I need that due to conflicting versions of containers.
Thanks!
